I suspended it, uninstalled vmware 16, installed vmware 15, re-started the guest vm, and everything is working fine. In fact, I didn't even stop my guest machine. I know it's not optimal to run this old software, but hey, it works! No issues whatsoever and performance is in top notch as I expected. But we don't live in such a world last I checked, so that's sort of moot.Īs a side note, I couldn't tolerate this anymore, and rolled back vmware 15. >If you had a real NVMe on the host AND the guest had a virtual NVMe adapter AND the virtual NVMe adapter worked as expected, then using a SATA virtual adapter would be non-optimal. I was afraid of the TRIM features since I don't want to nuke my nvme. > If you configure the guest OS to have a virtual SATA adapter as opposed to NVMe, then the performance problems will (ironically) disappear.

But the comfort of using Linux in Windows is missing me So I moved to a native Linux installation, because I make an intensive use of SSD (linux related compilations) and I don't want to break by NVMe disk in few months. So at some point, the VMWare SCSI virtual controller is translating SCSI commands to NVMe commands, so a lot of stuff are, let's say, mapped to a equivalent feature, or not mapped at all (like smart attributes, disk monitoring like internal temps), and I don't know what happen regarding NVMe specific commands dedicated to the NVMe life saving (let's say the TRIM equivalent, if such NVMe features are supposed to handle discard of files and so on).Īfter reaching the same conclusion than you, I looked at Windows DDA, for Direct Device Assignment, to test passing the whole NVMe drive to VMware, but this feature is supported on Windows Server only, and VMWare ESXi.

NVME disk => Windows 10 Host NVMe driver => VMWare SCSI controller => VMWare Guest Ubuntu SCSI disk The problem is that using the SCSI controller, you get something like this: Or possibly the virtual NVMe interface is inherently flawed in some way in the current VMware Workstation, and the QID timeouts are simply the noticeable symptoms of it.Įither way, I'd avoid using virtual NVMe drives in the current version of VMware Workstation until the problem is fixed on the VMware and/or Linux side. It's possible that the interface is fine, but that Linux is making an incorrect assumption about its operation that results in these QID timeouts. It's not clear why the NVMe device isn't working well with a Linux guest. And ironically, it may be slower than other (SATA/SCSI) interfaces due to periodic hangs of the guest OS. What's the difference though? NO QID timeouts, other disk-related errors, or other unexpected brief pauses in the VM.Ĭonclusion: The virtual NVMe interface provided by VMware Workstation is not ready for prime time. Now you have the exact same guest OS, whose disk is provided by the exact same physical disk backing on the host OS. Tweak grub if necessary to handle the change in the root.Add a SATA controller, using an existing VMDK as the disk backing.But let's dig deeper.įinally, take that same VM that is known to produce QID timeouts, shut it down, and then in VMware Workstation: Now, at those times look at the logs on the host OS for indicators of storage problems. Especially under load, the VM will see QID timeout messages, which are associated with a temporary pause of the VM kernel. Take a modern linux VM (kernel 5.4.92) configured with a virtual NVMe storage adapter. I think it's important to understand that the underlying storage backing on the host of the guest's virtual NVMe is probably irrelevant.

I can confirm that the Workstation Pro 16 virtual NVMe interface leaves something to be desired. I saw someone stating that the scsi controller was better regarding performance, but I was wondering if someone is using the NVMe controller type on Windows guest / Linux host, with a dedicated entire disk, and if it works? I tried various kernel/module parameters tuning, to turn off power saving regarding pcie/nvme core driver, use IO schedulers, etc. => On intensive disk usage, I get "nvme: QID Timeout, aborting"

VUbuntu2004 => Running Ubuntu 20.04 LTS, Samsung NVMe SSD 870 Evo Plus entire physical disk using NVMe controller type. => On intensive disk usage, I get "nvme: QID Timeout, completion polled" VUbuntu1804 => Running Ubuntu 18.04 LTS, Western digital NVMe SSD WDS500 entire physical disk using NVMe controller type. My host machine is Windows 10 Pro, running on AMD Ryzen 3800XT + NVMe SSD. I'm encountering NVme error in my guest Linux OS (nvme QID Timetouts) when I use a NVMe entire disk allocated to a virtual machine, I've made some tests, like this:
